Description

The flexibility compensating device that a kind of bender is used
Technical field
The utility model relates to the metal forming machinery in the mechanical engineering, more particularly, is to be used for the flexibility compensating device that the large-tonnage bending forming machine is used a kind of bender that obtains accurate deflection compensation on the workbench total length when bending.
Background technology
Effective configuration of bender work top is depended in the comprehensive utilization of bending machine die, and bender is through the bending function is implemented and accomplished to the setting in advance of mold shape, size and the motion process of bender oil cylinder up and down.
Because the raising of automaticity, can satisfy under the situation of task in rigidity and the intensity of metal forming machinery body, it is brief more good more that mechanical weight always designs.Often inevitably there are two defectives in bender in the bending process: the one, and the stressed slide block that causes of framework own produces the elasticity small deformation; The 2nd, the wearing and tearing of shaping dies.The former makes work piece produce deflection deformation, can't guarantee the total length uniformity of angle; The latter then influences the linearity of work piece.
For traditional be for the bender in application of force source with hydraulic pressure because the application of force of oil cylinder is inhomogeneous, in the bending process; Can make workpiece produce an amount of deflection in the longitudinal direction; And the overlength Bending Mould also through being usually used in the short workpiece of bending, can cause the only application of force in the middle part of counterdie of patrix like this, after long-term the use; Cause the workbench middle part recessed easily, also had a strong impact on the linearity of workpiece.
Thereby if address this problem that adopting gains in weight and strengthen the requirement that machine rigidity and intensity obviously can not meet modernized processing manufacturing industry, selection deflection compensation workbench is a kind of both economical way.At present, bender both domestic and external generally has two kinds of deflection compensation modes: a kind of is to be embedded in the hydraulic pressure deflection compensation in the workbench riser to many hydraulic cylinders; Another kind of then add the mechanical bending deflection compensation that protruding voussoir forms by many groups.It is few that the former adds salient point, and it is not high to add protruding precision, and leakage of oil easily, and manufacturing cost is high.The latter adds the convex curve ideal, but strict to part processing precision.
For this reason, the utility model adopts finite element analysis software oppositely to find the solution, and accurately calculates the sag curve of workbench; The array voussoir group that even distribution angle does not wait in the groove of workbench; Through moving voussoir, make middle protruding the sticking out of workbench, form corresponding sag curve; Reach the purpose of counter-bonification, thereby guarantee the linearity of workpiece.This deflection compensation mode has obtained general approval at present panel beating industry field.
